Secondary power supply box and tertiary distribution box
Primary: The main distribution panel, supplies power from the transformer. Let's make an example for clarity: A newly constructed residential area introduces a 10kV power line to a substation. These boxes feature bottom entry and exit cables, front-opening doors, and main busbars connected with copper strips for optimal contact. Many feeders leave substation in a concrete ducts and are routed to a nearby pole.

DC remote power supply system remote end
The remote end converts the DC high voltage to DC48V / DC280V / AC220V to the load (RRU), fiber optic repeater, small macro base station, micro-cellular base station, dry put, WLAN, PTN equipment, outdoor integrated access cabinet, EPON system (ONU) and other equipment. Power supplies offering remote sensing, also known as four-wire sensing, are able to compensate for these voltage drops. To achieve this, the voltage actually present at the DUT is measured using a pair of sense lines in addition to the force lines. However, existing research has problems such as ambiguous optimal power supply distance under different voltage levels and a lack of. But today, it's increasingly common for power supplies to be located far from the load—mounted on separate boards, routed across long traces, or connected through multiple connector transitions.

Add lightning protection to the power distribution box in the computer room
The power distribution box of the computer room should be equipped with SPD (anti-electromagnetic surge) protection devices to prevent the power supply of the computer room from being cut off due to electromagnetic pulses caused by lightning strikes. Our light-ning and surge voltage protection systems are per-fectly matched to one another and to the requirements in the different zones – from the air-termination device, which must arrest the full energy of a lightning strike, through to fine power protection, which eliminates the last voltage. one designed to protect the building structure and fabric and a second to protect sensitive equipment inside the building.
